There are both advantages and disadvantages between the two kinds of light sources. For COB integrated light source, the light-emitting surface is small, and light is more concentrated. It is packaged on a standard LED fixture, and has high requirements for cooling. Especially for some kinds of...
Within the broader category of LED video walls, there are also different packaging technologies. For more context, those include surface mount diode (SMD), integrated matrix device, and dots in place, but the real breakthrough happens elsewhere. It’s the chip-on-board or COB technology,...
